The local prosecutor is mum on what he calls the “quite voluminous” evidence against Peterson. (He pleaded not guilty.) One intriguing item: a powdery substance found in his boat that appears to be cement, which prosecutors may use to explain how Laci’s body stayed at the bottom of San Francisco Bay for four months. (Peterson’s mother has dismissed the powder as pieces of her son’s anchor.) Cops also reportedly found tidal data on Peterson’s computer for the area where Laci’s corpse was found, which could signal he wanted to know when to dump the body–or that he was going fishing, as he claims. Even behind bars, Peterson is said to be receiving fan mail from women who think he’s innocent–and a good catch. Which proves that other adage: hope springs eternal.
